Hexane, heptane, pentane, octane lwm tus neeg thiab manufacturers hauv Suav teb
N-Pentane, tshuaj formula C 5 H 12 , tus tswv cuab thib tsib ntawm alkane. N-pentane muaj ob lub isomers: isopentane (qhov kub ntawm qhov kub 28 ° C) thiab neopentane (qhov kub ntawm 10 ° C), lo lus "pentene" feem ntau yog hais txog n-pentane, nws cov isomer linear.
Kev siv ib txwm pentane
1. Nws yog siv los ua cov kuab tshuaj qis qis, cov yas muaj foaming tus neeg sawv cev, thiab tseem siv ua ke nrog 2-methylbutane ua roj rau tsheb thiab dav hlau, rau kev tsim cov dej khov nab kuab, tshuaj loog, rau synthesizing pentanol, isopentane, thiab qhov zoo li.
2. Cov qauv ntsuas roj chromatographic. Siv los ua tshuaj loog, hnyav, cryogenic tus pas ntsuas kub, thiab rau kev tsim cov dej khov, pentanol, isopentane, thiab lwm yam.
3. Rau kev npaj cov qauv roj, calibration gas thiab raws li molecular sieve desorbent.
4. Siv los ua cov kuab tshuaj, roj chromatography siv tshuaj thiab tshuaj loog. Kuj tseem siv rau hauv cov organic synthesis thiab hauv kev tsim khoom ntawm cov ntsuas cua sov.
5. Siv los ua cov kuab tshuaj los ua cov dej khov nab kuab, tshuaj loog, thiab ua ke pentanol, isopentane, thiab lwm yam.
